Abstract

BACKGROUND: Tracheal bronchus is a congenital malformation comprising an abnormal bronchus originating from the trachea or other bronchus. This malformation has been associated with recurrent pneumonia in children, but is rarely associated with infection in adults. Actinomyces species are rare causes of necrotizing pneumonias that often masquerade as malignancy, lung abscesses and tuberculosis.

METHODS AND RESULTS: A case involving a 46-year-old man with a tracheal bronchus and chronic pneumonia syndrome is presented. Bronchialveolar lavage and transthoracic needle biopsy demonstrated the presence of Actinomyces meyeri and Fusobacterium species.

CONCLUSIONS: The present article reports the first documented case of actinomycosis occurring in a patient with a tracheal bronchus.
